Plumbing Codes

Can the plumbers anwer this one for me?
I'm trying to get an idea of the differences in codes we are using, and where they are being used. It may help us to come up with better help in giving better local answers to local questions.

What state do you plumb in?
Which plumbing code do you work under?
Are there any modications to your code?

For me, the answer would be'
Washington State
UPC, Uniform Plumbing Code.

California.
2007 California Plumbing Code (title 24 part 5 CCR) . This is based directly on the 2006 UPC

There is an 8 page matrix detailing what sections and paragraphs are adopted/ or not adopted/ by certain specific state agencies, such as State Fire Marshall, Housing and community development, correction authority, Dept of Health services, etc.

Just as an example, Ch.3, general regulations,section 301 et al materials. SFM does not accept, and adds 311.11 prohibiting exposed plasitic piping in a room, if the flame spread exceeds blah blah ASTM blah blah. This applies to facilities under the jurisdiction of the SFM: small family day care, elder care facilities. high rise stuctures, hotels, motels, apartments.

Idaho. UPC. There are sometimes minor modifications, such as a 3" cross allowed for back-to-back toilets. (These days, I'd like to use something else - the fast-flushing toilets could be a problem.) We're allowed the high loop under the sink for a dishwasher hookup instead of a safe waste.

work in Oregon. use the 2003 UPC with amendments. also liscened in Washington and Idaho. All use the UPC. Oregon allows a santee on it's back for a vent connection, and the high loop for the dishwasher.

Prevent Contamination. Proper protection shall be provided to prevent contamination of food, water, sterile goods, and similar materials by backflow of sewage. When necessary, the fixtures, device, or appliance shall be connected indirectly with the building drainage system.

Ohio is slowly adapting to requirement of Air Gaps on dishwashers. I can only speak for the some of the counties in southern ohio. I just moonlight over there but a supply house in clermont county told me that they have to supply air gaps as they are required.

Son a plumber and builder (do as much of the plumbing/mech as time allows)

Denver Colorado

IRC 2003

Quite a few in an addendum.

As I was reading about the post with the fellow who got gigged on venting the horizontal 2" run with his san-t on its back, it made me think about what code his municipality is using (or maybe recently switched from) and what the ages and experience of the two inspectors were. We just switched over to the IRC about 3 years back from the UPC and the venting has given lots of folks fits because it is different. Easier in most ways but different and different logic.

Older inspectors who were wrenches get it and offer flexibilty, particulalry on remodeling. Newer ones tend to be more by the book.
